Shardeum Overview

Shardeum is a blockchain that supports EVM smart contracts.

For more general information on Shardeum:

What is Shardeum?

Cross Shard Composability with Linear Scaling

Shardeum is sharded, allowing the network to scale linearly with more nodes. Horizontally scaling in this fashion allows for high transactions per second at low gas prices.

Wallet Setup For Using Shardeum

You will need an EVM wallet like Metamask to:

  -pay for transaction gas fees
-transfer tokens
-interact with smart contracts

Deploying Tokens To Shardeum

All EVM based token standards are supported on Shardeum (since Shardeum is EVM compatible). Popular tokens supported on Shardeum:

ERC-20 (Fungible Tokens)

ERC-721 (NFTs)

ERC-1155 (Token Emulator)

Cross Shard Composability Communication With EIP-2930

Smart contract addresses that don't have the same prefix are deployed to different shards. The EIP-2930 accessList is used for shard routing contracts on different shards and is automated inside Shardeum nodes.

Integrate File Storage Into Shardeum

We recommend users to use decentralized file storage standards like IPFS and Filecoin.

Files stored on IPFS can be used in contracts to deploy contracts with CID values as shown in this example:
